Passive Voice Activated Cortana on Lumia 830???

Now that Lumia 830 is out on AT&T, did anyone get a chance to test if it supports passive voice activation? Articles online seem to be contradictory. Some saying it requires SensorCore, which is present in SnapDragon 400, some mentioning it requires SnapDragon 8x and others mentioning the requirement of both. So, I guess the only way of testing it is to have a actual hands-on. Has anybody been lucky on that to test it???
